ABSTRACT

BACKGROUND: Rib cage remodeling has shown promising aesthetic results as a new technique for body contouring yet risks and complications associated with the procedure have not been well established. The aim of our study is to assess safety, efficacy and patient satisfaction rate associated with a new surgical technique for waistline definition. METHODS: We looked into our records for patients who underwent waist narrowing through a new rib remodeling procedure with osteosynthesis of the 11th and 12th ribs; from October 2022 to June 2023. Follow up was carried out at 1 and 3 months after surgery. Outcomes were evaluated based on waist and hip measures, body images, pain and a patient satisfaction survey. RESULTS: A total of 27 consecutive patients were included in the analysis. Our technique resulted in a significant reduction in waist circumference, as evidenced by a decrease of 12.1 cm and 13.0 cm at the first and third month respectively (p<0.005). A reduction of hip circumference of 6.2 cm and 8.7 cm was also reported. A high patient satisfaction rate was reported. Postoperative complications included only one case of wound dehiscence and one case of mild pain. Pain levels were also reduced, with a mean pain score of 2.4 at week 1 and 0.26 at month 1. CONCLUSION: Rib osteotomy with osteosynthesis emerges as an innovative, safe, and reliable approach for waist narrowing. Our results suggest that this technique can be applied to a wide variety of patients and presents might entail significant advantages compared to those from other techniques. TYPE OF STUDY: Retrospective cohort. Level of Evidence: III.

ABSTRACT

Ganglioneuromas (GN) are benign neuroblastic tumors that arise from neural crest cells. Since they present with nonspecific symptoms, diagnosis is often incidental. We are reporting a case of an adult appendiceal GN incidentally found during rectal cancer surgery. A 42-year-old male was diagnosed with recurrent rectal cancer after experiencing urinary difficulties and buttock pain. A multiple-stage pelvic exenteration was carried out after neoadjuvant chemotherapy and chemoradiation. Prophylactic appendectomy was done during the course of surgery, and pathology reported an appendix with GN at the distal tip. GN are often found incidentally and rarely cause appendicitis. Depending on their location and size, they might become symptomatic. While there is some controversy on whether surgery is the treatment of choice for all GN, diagnosis is rarely apparent preoperatively, and all appendiceal masses should be resected.

ABSTRACT

BACKGROUND & AIMS: The incidence of Crohn's disease (CD) continues to increase worldwide. The contribution of CD4+ cell populations remains to be elucidated. We aimed to provide an in-depth transcriptional assessment of CD4+ T cells driving chronic inflammation in CD. METHODS: We performed single-cell RNA-sequencing in CD4+ T cells isolated from ileal biopsies of patients with CD compared with healthy individuals. Cells underwent clustering analysis, followed by analysis of gene signaling networks. We overlapped our differentially expressed genes with publicly available microarray data sets and performed functional in vitro studies, including an in vitro suppression assay and organoid systems, to model gene expression changes observed in CD regulatory T (Treg) cells and to test predicted therapeutics. RESULTS: We identified 5 distinct FOXP3+ regulatory Treg subpopulations. Tregs isolated from healthy controls represent the origin of pseudotemporal development into inflammation-associated subtypes. These proinflammatory Tregs displayed a unique responsiveness to tumor necrosis factor-α signaling with impaired suppressive activity in vitro and an elevated cytokine response in an organoid coculture system. As predicted in silico, the histone deacetylase inhibitor vorinostat normalized gene expression patterns, rescuing the suppressive function of FOXP3+ cells in vitro. CONCLUSIONS: We identified a novel, proinflammatory FOXP3+ T cell subpopulation in patients with CD and developed a pipeline to specifically target these cells using the US Food and Drug Administration-approved drug vorinostat.

ABSTRACT

Background: High-definition liposculpture allowed plastic surgeons to achieve better aesthetic results by carving the underlying muscles and contours in a new way. Several authors have improved the original technique by adding other procedures and new technologies. We designed a new improvement by incorporating bone transformation surgery to overcome the lack of silhouette at the waist and, as a result, optimize the breast-waist-hip ratios. Methods: We carried out a prospective multicenter study, with five different surgeons performing the same rib remodeling technique for waist definition. We used an ultrasonic piece for costal corticotomy and real-time ultrasound imaging to perform green-stick fractures over the last two or three floating ribs. Ours is a new technique based on the prior one described by Kudzaev. Results: We reported 131 consecutive patients who were enrolled in this study. Waistline diameter decreased an average of 8 cm after surgery (P < 0.05). Most patients were women (n = 125, 95.4%). No major complications were reported. Most common complication was prolonged pain, with only three cases of contour asymmetry, all of which were attributable to noncompliance of constantly wearing the corset + compressive garments. Patients reported a high satisfaction rate and fast recovery (Body-QoL survey). Conclusions: Ultrasonic- and ultrasound- assisted indentation surgery of the thorax is a safe and reliable technique for waistline definition, with a high satisfaction rate, almost-invisible scars, and minimal risk for complications. Incorporation of high-definition liposculpture to rib remodeling opens up a new horizon for bone structure modification surgery (S-high-definition remodeling) that can be safely performed for patients who seek better aesthetic outcomes in body contouring.

ABSTRACT

Radiofrequency is frequently used for skin rejuvenation, localized fat elimination and cellulite treatment. It prompts the expression of thermal shock proteins that lead to dermal thickening as a result of collagen synthesis. The authors report a histological and clinical analysis of the arm subdermal changes before and after bipolar radiofrequency treatment plus liposuction to determine their benefits for arm contouring. Methods: Inclusion criteria included patients with stage 1, 2a, and 2b brachial ptosis (Duncan classification) and upper limb fat deposits who were considered candidates for third-generation ultrasound-assisted liposculpture plus radiofrequency-assisted lipolysis/skin tightening. Arm subdermal tissue samples (5 mm³) were analyzed before and after the intervention. We used 10% formaldehyde for tissue fixation and stained each sample with hematoxylin/eosin, Masson trichrome, and antibody markers against the cell cycle Ki-67 protein. Results: We analyzed a total of 12 biopsies from six patients who meet the inclusion/exclusion criteria. Histological findings with hematoxylin/eosin revealed hyperplastic and metaplastic changes with focal distribution within the papillary and reticular dermis. Masson trichrome staining showed an increase of the characteristic basophilia of thin type-I and type-III collagen fibers. In contrast, molecular analysis reported an increase in fibroblast activity mediated by the activation of the heat shock protein HSP47. Conclusion: Radiofrequency may be a great alternative to improve skin retraction in patients with mild to moderate brachial dermatochalasis through the activation of HSP47 heat shock protein and the production of type-I and type-III collagen.

ABSTRACT

The abdominoplasty procedure poses a number of unique challenges. If the stigmata of the operation is to be avoided, careful planning and surgical execution are required. We describe our experience in full and mini abdominoplasties with a 360-degree approach, involving all muscular groups and body segments as described by high-definition liposculpture. Selective fat grafting is also safely performed in specific areas to improve projection and volume.
